faster dvd writers

[Guzo]

I'd like to know when are faster drives to come

like 6× or 8×

C Ya fellas

Fast CD Burner = Burns a disc 2:30
DVD capacity = Slightly over 6X a CDR

Time to burn 6 CDRs = 15 minutes
Time to burn 1 DVD = 15 minutes

Seems like it's pretty fast already no?

It is fast! But I would love to burn a DVD video disc in 2:30. That be sweet.

[Guzo]

my wish is:

8× DVD (accepted stardard)
6-8 DVD RW (also standard)

24-32 CD-R
16× CD-RW

and 40× CD read
and 16×Dvd read

and excellent DAE and also DVD ripping

I could be to demanding

Last week I went to BenQ's website to read about their dual DVD burner. I think it was in their news section they mentioned they are currently working on a x8 drive that should be out by the end of 2003. This reminded me of another news article a few months back that stated either a group of manufacturers or one specific like Sony were coming out with x8 drives by the end of 2003. Although Sony has a new drive DRU-510A and several other company's have new dual DVD burners out now - it makes you wonder.

Just to play it on the safe side, I'm getting a DVD-Rom drive now and waiting until November/December to see if there are x8 drives coming out. If they do come out then I'll buy it then.

I'd rather have a 4x writer with faster CD reading and writing speeds. You'll probably have to sell a kidney to afford 8x DVD media at first.

Another thing is that you will have to defragment your drive more often, if you work with large files a lot and you want to burn DVDs at 8X.

Also home DVD players (especially existing models) may (not sure on this) have trouble reading discs burned at 8X?

why's that?
if the burners are well designed and make good quality burns, it shouldn't matter, should it?

It is not a problem with the burn quality.
The media is apparently different.
For example, a Maxell rep said that some older DVD players (even made only months before 4X media came out) might/would have problem reading the new media.
8X DVD recordable media is bound to be even more different physically/chemically than 4X.

Once again, I am not sure this will be the case. I am only going by what a Maxell rep said about 4X media about 6 months ago.

Doesn't matter to me since I don't own a DVD player. I'm been buying DVDs since November so I wanted to get a DVD-Rom drive now so I can start to watch them. I might get a DVD player to hook up to my tv next year so maybe those models can handle the 8x media.

It depends on your preferences and how your going to use the drives. This is where I differ from alot of other people. I have a 52x CD-Rom drive which I use to play audio CDs and to install software. I also have a CD-RW drive - the plextor 24x/10x/40x which I use to install software and burn CDs ( I find that if I play audio CDs it is noisy. )

If I were to get a dual DVD burner, say the Sony DRU-510A, its CD speeds are 24x/16x/32x which is very close to my CD-RW drive. I would use it to play DVDs (mainly DVD movies), to burn DVDs, and to play audio CDs. However I would probably not use it to burn CDs since that is what my CD-RW drive is for.

Also I was planning on upgrading my CD-RW drive to the Plextor Premium which has the current and fastest CD speeds: 52x/32x/52x which is almost twice as fast. I don't see a point in using a DVD burner to burn CDs when I have a CD-RW drive that is faster and better suited to burn CDs. In other words a DVD drive should be used for its main purpose DVDs and a CD drive should be used for its main purpose CDs.

The fact that DVD burners can also burn CDs is great but to me that is an "extra" or "side " feature that is nice to have but I'll probably would rarely use. It would only come into play if I wanted to burn 2 CDs at the same time ( since I have never done that, does that mean you have to run 2 burning programs at the same time - one for each burner? )

So, in the end, if I had a choice of getting a 4x DVD burner with fast CD Speeds or an 8x DVD burner with regular CD speeds - no contest, I will always take the 8x DVD burner every time.

An 8X burner is going to have to be very accurate isnt it, 8X is around 11MBs to shovel on the the disc (48X CD =7.2MBs)

[Ian]

I'm not sure what you mean by accurate, but yes, it will use a lot of I/O bandwidth. Maybe we'll finally see a UDMA 66 writer...

At 1X, a DVD disc transfers data at about 8.725 M bits/sec. Therefore, at 8X the transfer rate is 8.725 MB/sec.

1X = 1380KB x 8 = 11040KB / 1024KB = 10.78MB (AKAIK anyway)

By accurate, sorry i meant tracking and power etc. at the speed it will be going will the laser be able to hit the sweet spot and be quick enough and with enough umph to make a big enough dent in the dye for it to last more than a week without turning the heat up that much it cocks it all up? Of course it will but i bet it aint going to be cheap.

[Ian]

I'm betting that these new drives will use CAV instead of CLV. They'll probably spin as fast as most of the 4x currently on the market. But yeah, I see your point about the dye. They've gone through all of this with CD's. Hopefully they learned something.

[I Have Piles]

8X DVD is miles faster than the fastest CD burners no matter which figures you use and when you take in to account the write laser has to do it for the same as 6 CDs but in one go at such a high speed without recalibrating, it is a lot to ask, although like i said it is obviously not impossibe, far from it.

If i am wrong i dont mind, nothing is set in stone and i am but a single man with an opinion.

[Morpheus]

Hmmm. Wouldn't the point being that CD-Rom drives topped out at 56x, CD-RW drives have now reached 52X and the 8x DVD would have reached this area of around 48x(+) CD?

The limiting factor with CD-RW and CD-ROM drives has been rotation speed. DVD writers haven't come close to touching this, especially when you consider 1x with a DVD-ROM is about 1500RPM (anyone know the exact # off the top of their heads?). Some CD-ROM drives rotate as fast as 12,000 RPM or more. With some of the new 16x DVD-ROM drives rotating at only 9500RPM, you can see that there is a lot of potential here.

[Kennyshin]

I want 8x DVD+RW media.

You would be referring to the 1X speed of a DVD at the inner diameter of the disc, since the RPM requirements for the same 1X speed at the outside of the DVD disc would be far less. The scanning velocity of an 80 minute CD-R disc is about 1.2 m/sec. DVD discs have scanning velocities of 3.49 m/s for single layer and 3.84 m/s for dual layer discs. So as a rough approximation, a dual layer DVD would be turning at 3.2 times the rate of a CD(R) for the same reading speed. Using an estimated 1X CD speed of 530 RPM at the inner hub, the same 1X speed on a dual layer DVD disc might be as much as an approximate 1,696 RPM. For a single layer DVD the same 1X speed at the inner hub might be as much as 1,541 RPM. In answer to your question, I don't know that there is an exact RPM number for DVD discs. I have seen the inner hub speed for CD's stated from 500 to 580 RPM. There are are even more variables involved with DVD, so we may have to settle for estimates. A 1X DVD speed of 1,500 RPM at the inner hub of the disc is close enough for our purposes.

The high speed ratings for DVD drives always use single layer discs, since dual layer discs can't be read at the maximum advertised speeds.

Some CD-ROM drives rotate as fast as 12,000 RPM or more. With some of the new 16x DVD-ROM drives rotating at only 9500RPM, you can see that there is a lot of potential here.

In my opinion, the CD-ROM drives that operate at 12,000 RPM are the ones that are more likely to provide shattered discs, extreme noise, and a short operating life with generally unreliable results. Since 9,600 RPM is suitable for 48X CAV CDR recording, I disagree that there is a lot of RPM potential left for DVD speeds. 52X seems to be the stop limit for responsible CD-RW manufacturers, and DVD drives reading at 16X are operating at a rotation speed close to an equivalent speed of 47X with a CD(R). There may be a little room left for speed, but not much reward in doing so.

The main constraint right now with DVD is not reading speed, but writing speed. There may be significant potential left to increase recording speed as the technology matures.

[Morpheus]

I figured it would be something like that. DVD-Rom drives are capable of 16x DVD read speed and 48x CD read speed. As for CD-RW drives Maxell (?) stated that 48x speed was already fast enough and they weren't going to produced 52x media as that speed was so fast that you might run the risk of the disk shattering. ( Which reminds me of an article I read 2 years ago shortly after I bought my 52x CD-Rom drive - that you shouldn't push the disk passed 40x speed as you might run the risk of it shattering - never heard of this happening though. )

CD-RW drives are pretty much topped out. The only advancements left is to bring the CD-RW speed ( currently at 32x ) up to 52x, so the drive will be 52x/52x/52x speed. ( probably 32x -> 40x -> 48x -> 52x )

As for DVD-Rom speed, if 16x is the equivalent of 48xCD then wouldn't DVD 17.3x be the equivalent of 52x CD read speed? Since the DVD read speed is pretty much at that barrier then all they need to do is bring the write speeds up to that level - so currently they are at 4x then 8x is the next step, then 12x, and then finally at 16x ( for a 16x/16x/16x/16x DVD write speeds. )
